atory. The Photographic plate had

The manufacture of solid carbonic
acid gas is said to have become
settled industry in Berlin. 1t is put in
small cylinders and if kept under pres
sure will last some time; that is a
cylinder one and half inches in
diameter and two inches long takes
five hours to melt away into gas.
If the statements which come from
Brazil on the subject are trustworthy,
the Freire system of incubation against
yellow fever certainly seems to be effica-
cious. The mortality from the disease
in Rio de Janeiro is said to be ten times
as great among those who have not
been treated by DR.. Freire's method as
among persons who have been inocu-
lated.-M Y. Ledger.

We learn from the Pittsburgh Iron
World that Pittsburgh steel makers
have established agencies for the sale
of the finer grades of steel suitable for
making cutlery in Europe, India and
Australia. Their sales have been so
considerable as to practically guarantee
an established trade. Steel has been
sold in competition with English-made
steel at the same prices, and, the World
says, 1.-THE prices, under the circum-
stances. were entirely satisfactory to
the producers.
Faye. the French mcteorologist,
thinks the movement of q tornado is
not ascending. rs some scientists sup
pose it to be, but descending, pene-
srating the lower layers of the atmos-
phere like corkscrew. The destruct-
Eve effects of these storms are ascribed
Co the violent shock occasioned by the
collision of the descending spirals with
the ground. and the energy is not APP
parently lcsscned by this contact, mas
much as it is constantly renewed from
above, and transmitted to the earth by
the rotary motion downwards. M Y.
